s PEc'IFIoATIo'N forming part of Letters Patent No. 613,674, dated November 8, 1898.

Application filed January 26,1897. SerialNo. 620,782. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN CAMERON GRANT, a citizen of England, residing at Albert Lodge, Albert Place, Kensington, London, in the county of Middlesex, England, have in vented certain newand useful Improvements in Rims or Fellies for Oycle or other Road Wheels, of which the following is a specification.

My invention has for its object the construction of a rim or felly for cycle and other road wheels that shall possess great lightness, combined with strength, toughness, and elasticity. For this purpose I construct such rims of the combination of an inner body or core made of paper-pulp or papier-mach, preferably formed of rhea fiber, (such as Bohemem'a m'oeaJ and an outer covering of a woven fabric, preferably formed of rhea fiber, which is cemented to the paper core, the whole being subjected to compression in suitable molds. By this means an exceedingly strong, tough, and yet light rim is produced. Such rims may be made of any configuration employed in the manufacture of cycle and other road wheels.

Figure 1 is a cross-section of a rim, showing one form of my invention; and Fig. 2 is a partial perspective view of the tube before it is compressed into form.

In Fig. 1 I show a rim constructed in accordance with my invention and shaped to receive a tire such as set forth in my copending application, Serial No. 620,778, filed January 26, 1897, wherein two auxiliary pneumatic tubes are introduced and expanded in the tubular channels A of the rim A. This consists of the core a, of paper material, preferably of rhea fiber, and an internal and external covering a d of woven fabric, preferably of rhea-duck. This rim is in the first instance made of the tubular form shown at Fig. 2-, which'after being subjected to the required degree of compression is bent in molds, so as to assume the form at Fig. 1.

Having thus described the nature of this invention and the best means I know of carrying the same into practical effect, I claim- A wheel-rim consisting of a tube composed of paper material having an inner and outer layer of Woven fabric, said tube being compressed and collapsed into the desired form; substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 12th day of January, A. D. 1897.

JOHN CAMERON GRANT.
